Nwadike, a lifelong runner, was inspired after seeing the horrors at the Boston Marathon in 2013.

“I wanted to figure out a creative way to pay my respects, so I said if there was a bomb there I'm just going to be the ‘love bomb!'" he said. "The following year I went out to the race and I just decided to hug people.”

He attributes his deep empathy and desire to help others from being homeless as a child.
